Defective Connectors
This product is unfortunately totally defective. The filter itself may work okay, but the plastic shroud connectors and tubing are prone to breaking off within 24-36 hours of installation. I thought perhaps the first model may have just been randomly defective and bought a second. Both models broke at the same point going to the cold water valve. This defectiveness could have caused major damage as it will constantly spew water until you can get the valve turned off. I would not recommend this s...
We installed this about 5 weeks ago ago and it worked fine for about a week and a 1/2. Then one day we heard water coming out all over under the sink. A hose had blew out of the filter itself which isn’t even supposed to come at all! Lots of water everywhere. I really thought the water tasted great before the filter blew out. So disappointed

Connection Methode Stinks
The filter unit itself is good. The issue is it uses a cheap plastic hose and push-in plaster connector on the filter. Installed the filter under the kitchen sink. Was working for about six hours when water started gushing out from under the sink. The output side plastic hose and connector had dislodged from the filter unit. Called their customer service and was told I needed to send them a video of the problem. All I wanted was a replacement for the push-in connector but was told I needed ...

Verified Purchaser
Although it does positively affect water quality, as another reviewer mentioned, the connections become leaky fairly soon after installation, with my input hose altogether failing after only 48 hours of use.
Thank you for sharing your feedback with us. We’re glad to hear the system improved your water quality, but we’re very sorry to learn about the leaki...

There is a difference
It does take the chlorine taste and the smell away. My coffee tasted different also.
